Date Dec. 8, 1994A method is provided for changing over to a standby link for a transmission device for the bidirectional transmission of digital signals. To implement the bidirectional changeover to the standby link as quickly as possible, control information is transmitted, as a rule, in only one step between the terminals (1, 3). In the event of a mismatch between information on the state of the respective local switching device formed locally and received (K2) from the distant station, the local receiving device (14, 34) is connected to the operating link (21) for eliminating the switching fault.</p> |
